GUN SIGHT Filed Dec. 6, 1944 FL v Patented June 18, 1946 httiitli ace UNITED STATES PATENT OFFICE 1 This invention relates to a sight for a gun and more particularly to an improved sight embodying novel adjustments for elevation to determine yardage and transverse adjustment for windage. An object of the invention is to provide a rear sight for a gun in which the sight is adjusted vertically through angular moyement of the sight and to provide means for maintaining the sight in a plane parallel to the gun barrel regardless of its vertical adjustment.

Another object of the invention is to provide means for minutely adjusting the vertical or transverse position of the sight relative to the gun barrel; there being also provided mans for permitting rapid adjustment to a given degree and subsequently a finer adjustment for accurately positioning the sight to an exact adjustment.

Other objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawing in which:

Fig. l is a fragmentary side view of a gun having my improved sight mounted thereon;

' Fig. 2 is a perspective view of the sight; and

Fig. 3 is an exploded view of the parts shown in position for assembling.

Referring to the drawing I have shown a portion of a gun having my improved sight mounted thereon. The sight has a base portion I2 adapted to be received on the barrel of the gun l6 such as by a screw, not shown, extended through an opening 14. The base l2 has spaced, upwardly extending ears I6 and [8 provided with openings 26 which pivotally support a rotatable bushing 22.

The bushing 22 is tubular and has a slot 24 extending through the wall thereof throughout the length thereof and an oppositely disposed notch.26 in one end face of the tubular bushing 22. The opposite end face is provided with an annular flange 28 having its outer periphery provided with arcuately faced notches 36 for engagement with screw threads. v

A sight carrier 32 has one end provided with a sleeve 34 having an outer diameter substantially equal to the inner diameter of the tubular bushing 22 and isfreely slidable longitudinally in the bushing 22. A reduced portion 36 of the sight carrier 32 is attached to the outer periphery of the sleeve 34 and is received in the slot 24. A locking member 38 is slidably mounted on the carrier 32. Its bottom surface is formed arcuate to fit the outer periphery of the tubular bushing h 22 and has one face provided with an indicator mark 46. A washer 42 rests on the locking member and a sleeve 44 screw threaded to the carrier 32, looks the member 38 into tight frictional enagement with the outer periphery of the bushing 22 when the parts are assembled and the sleeve screwed downwardly on the carrier 32.

The inner periphery of the sleeve 34 is screw threaded and receives a threaded shaft 46 having its outer end provided with a knurled flange 48. The inner end of the shaft 46 is threaded into a knurled flange 56 and when finally assembled is locked thereto by a screw 52 entering a threaded opening 54, partly in the shaft 46 and the flange 50. A washer 56 is arranged between the inner surface of the flange 48 and. the outer surface of the ear I 6 and is provided with radially extending lugs 58 which are received in the slot 24 and the notch 26. Shoulders 66 are provided on the inner faces of the flanges 48 and 50 which fit within the opposite ends of tubular bushing 22.

When the parts are assembled, the flanges 48 and 50 and shaft 46 are rotatable relative to the housing l2, bushing 22 and sleeve 34 and rotation thereof causes the sleeve 34 to be moved to the left or right by the screw threaded connection between the shaft 46 and sleeve 34. Axially spaced markings 62 are formed on the outer periphery of the bushing 22 so that by moving the carrier 32 the mark 40 indicates the transverse position of the carrier.

The outer end of the carrier 32 is bifurcated providing a space for the reception of a swinging arm 64 pivotally supported on a pin 66 which is screw threaded into one side of the bifurcated end of the carrier 32. The arm 64 has a threaded sleeve portion 68 which receives a peep sight I0 threaded therein. The arm 64 is further provided with an extension 12. A U-shaped link I4 is pivotally supported at its looped end in the extension 12. The opposite ends of the link 14 are received in one pair of openings 16 in the ears l6 and l 8 forming a parallelogram connection for the peep sight 10. It will be understood that as the carrier is pivoted about the axis of the shaft 46 and bushing 22, the link 14 retains the peep sight 10 in a horizontal position or in a position parallel to the gun barrel.

Spaced pairs of openings 16 may be provided for positioning the free ends of the links 14 whereby the initial angular relation between the axis of the peep sight it and gun barrel may be varied. This is important in connection with the mounting of the device on the gun. In some instances the sight is mounted on a surface out of the plane of the gun barrel as shown on the drawing and in others it may be mounted on the barrel.

A threaded member 18 has one end axially fixed but pivotally supported in a member 80 which member is pivotally supported in the housing 12. A spring 82 normally urges the threaded member 18 into threaded engagement with the arcuately faced notches 30. Aknurled flange 84 is received on the upper end of the threaded member 18 for rotating the member I8. Such rotation causes rotation of the bushing 22 and consequent angular movement of the carrier 32. In order to make a quick adjustment the member 18 is pivoted away from the notches 30, against the spring 82,

and the bushing may be rotated by turning the a flanges 28, 50 and 48 with the fingers. After an approximate angular adjustment has been made the member 18 is released and the spring 82- urges the threads of the member 18 into engagement with the notches 30 whereuponlvery fine'adjustments of the angular position may be made. i

It will be understood that various changes including the size, shape and arrangement of parts may be made without'departing from the spirit of my invention and it is not my intention to limit its scope other than by the terms of the appended claims.

Iclaim:

1. A gun sight comprisingza base portion, a pair of spaced ears carried by said base having aligned openings therein, a' tubular bushing pivotally supported in the openings of aid ears, a

for rotating said bushing for causing angular movement of said carrier relative to said base, and means for rotating said shaft for causing transverse movement of said carrier relative to slot in aid bushing, a threaded shaft extending axially through said sleeve and bushing in screw thread engagement with said sleeve, means for rotating said bushing for causing angular move- -ment of said carrier relative to said base, means for rotating said shaft for causing transverse openings'therein, a bushing pivotally supported 7 in the openingsof saidears, an'annular flange threaded sleeve within said bushing and movable I axially therein; said bushing having a longitudinally extending slot through its Wall, a sight carrier secured to said sleeve and extended through carried by said bushing having its outer peripheryprovided with notches for engagement with screw threads, a sight carrier on said bushing, and a screw threaded member having its axis at right angles to the axis of said bushing normally in screw thread engagement with the notches on said flange whereby rotation of said threaded member causes angular movement of said bushthe slot in said bushing, a threaded shaft extend-o. ga ing.

ing axially through said sleeve and bushing in screw thread engagement with said sleeve, means THOMAS SIEDLARZ.
